Re: request.session in template tag?
Thanks to a comment on my blog: the below is null and void: the
request object can be retrieved directly from context: context
['request'].

Re: request.session in template tag?
If you just need the request obj passed to all pages. I use this in my
URLs:
# Custom Direct to template - carrys the request object
def direct_to_template(request, template):
from django.shortcuts import render_to_response
from django.template import RequestContext
return render_to_response(template, {'request': request},
context_instance = RequestContext(request))
urlpatterns = patterns('',
(r'^$', 'urls.direct_to_template', {'template': 'index.html'}),
)

Hi your best bet is to do the following - I used this for something
else but you'll get the idea:
from django.template import resolve_variable
from django import template
from django.template import Library, Node
register = template.Library()
class AlertNode(Node):
def __init__(self, request):
self.request = request
def render(self, context):
request = resolve_variable(self.request, context)
# Do something with the session
var = request.session.get('js_alert', None)
if var:
del request.session['js_alert']
return str('alert("%s");' % var)
else:
return ''
@register.tag(name="get_js_alert")
def get_js_alert(parser, token):
try:
tag_name, request = token.split_contents()
except ValueError:
raise template.TemplateSyntaxError, "%r tag requires exactly
one argument" % token.contents[0]
return AlertNode(request)
# Usage: {% load js_tag %}{% get_js_alert request %}
You now have acces to POST, GET and SESSION ect in your templatetag.

Re: trouble with Django and javascript
I personally feel you should look into doing the post via Ajax, pass
your form field values into an array and unpack the values in your
view:
ie:
function AjaxSubmitForm(formdata){
$.post('/ajax/some-view/'+formdata+'/', function(data){
if(data == 'done'){
d.body.innerHTML = "This is a test";
}
});
}
JSON would be a better option but this will work well. See more at:
http://docs.jquery.com/Ajax

Re: @cache_control() and @never_cache not working
Thanks for the help Thomas, unfortunetly it wouldn't be within budget to port this site over to 1.0. Will however look into the link you provided.

@cache_control() and @never_cache not working
Hi, I'm pretty new to django so please bear with me. The Server: lighttpd python 2.5 django 0.96 The Code: >>> settings.py # Cache settings CACHE_MIDDLEWARE_SECONDS = 5*60 CACHE_BACKEND = 'file:///var/www/data/some_project/tmp/file_cache/? timeout=300&max_entries=500' # Middleware MIDDLEWARE_CLASSES = ( 'django.middleware.cache.CacheMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.doc.XViewMiddleware', ) >>> views.py @never_cache def some_view(request): ... @cache_control(no_cache=True, max_age=0) def some_view(request): ... Okay so I think i've got the above right but all the views with the above decorator cache anyway and as this is being used for clients to upload and manage property listings. I'm stumped can anyone help? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.
